George Clooney better watch his back around Stacy Keibler

George Clooney and his new girlfriend, former wrestler Stacy Keibler, aren't afraid to fight.

It looks like George Clooney's new lady love Stacy Keibler is a knockout in more ways than one. The actor, who has been dating the leggy model and actress for a few months now, says he's worried about getting into a fight because she is both taller and stronger than him.

"She's very tall," Clooney told E! News at the premiere of The Descendants on Wednesday night, when asked about Keibler. "And she can take me two out of three falls. She can kick my a*s."

But Clooney says he doesn't have to worry too much about feeling the wrath of Keibler's temper because she's such a lovely person.

He said: "She's a nice girl. She really is."

It's not too surprising that Keibler can hold her own while sparring with Clooney, as she wrestled for both World Championship Wrestling and World Wrestling Entertainment. She made her fighting debut in 2007, wrestling in a wedding gown at an event called Bash at the Beach. During her time as a wrestler, Keibler earned the nicknames "Super Stacy" and "The Legs of the WWE."

And while Clooney hasn't been one to kiss and tell about his relationships, he is uncharacteristically opening up a lot about his hot girlfriend. The actor went on the record earlier this month to say that he's not bothered about Keibler's Twitter posts about their relationship.

"She can do whatever she wants," Clooney told Rolling Stone of Keibler's tweets. "I rarely tell anybody what they should be doing with their life."

It looks like Keibler might actually be the one to tie Clooney down (perhaps in more ways than one). The actor introduced his girlfriend to his parents at the movie premiere.
